FUEL-PRESS.

Specification of Letters Patent. Pat nted D 13 112 121 Application filedJune 21, 1920. Serial No. 390,315.

To all whom it may concern:

My present invention has'for its object to provide an extremely simpleand highly eiiicient fuel press for use in the manufacture of briquets.The improved fuel press is intended for general use, but especiallyadapted in manufacturing briquets from the waste in fiber factories.

To the above end, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claim.I

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings: 7

Figure 1 is a plan view of the improved fuel press;

Fig. 2 is a side elevation of the same;

Fig. 3 is a transverse section taken on the line 38 of Fig. 1;

Fig. 4 is a longitudinal section taken on the line 4-4= of Fig. 1, on anenlarged scale; and

Fig. 5 is an end elevation of the parts shown in Fig. 4.

The frame of the improved fuel press includes two laterally spaced sidemembers in the form of connected channel bars 6, the flanges of whichare turned outward. These side members or bars 6 support a heavyrectangular one-piece die-block 7 mounted be tween vertically spacedpairs of angle bars 8 rigidly bolted to said side members and thedie-block. Extending longitudinally through the die-block 7, from theone end to the other, are, as shown, three laterally and horizontallyspaced die seats 9. Rigidly secured in each die seat 9, by pressure orotherwise, is a bushing 10, which extends the full length of the dieseat and out of the delivery end thereof. The projecting delivery endsof the bushing 10 are externally tapered and longitudinally split at 11at circumferentially s aced points. The tapered ends of the bushlngs 10are provided with screw-threads at 12 to receive correspondingly taperednuts 13 for contractine' the delivery end of said bushings. a

Longitudinally extended rectangular feed passagewavs 1 1- are formed inthe top of the die-block 7 and bushing 10, near the receiving end ofsaid bushings. Materials 1from which the briquets are formed, are doilvered into the feed passagewavs 1 1- by means of a hopper or othersuitabie means not shown. Pliingers 15 mounted in the b ushings l0 andsecured to cross head lamounted between the vertically spaced pairs ofangle bars 8, which as guide rails therefor, and said cross head is alsoheld by the side members ,6 for straight-line sliding movement.

The following connections are for operating the cross head 16, towit:

Journaled in bearings 1?, on he C members 6, is a driven shaft 18 havirkeyed to 1ts intermediate portion, between tlie 1 members 6, a pulley19, over which runs a drlving belt, not shown. The ends of the shaft 18are extended outward of the side members 6 and have keyed to each end trereof a fly-wheel 20, between which and the r spective side members 6is keyed a pinion 21. A counter-shaft 22 is journalcd in the bearings 17and keyed to the ends thereof are gears 28, which mesh with the pinion21. To the intermediate portion of the shaft 22, between the sidemembers 6, is keyed a pair of pinions 24:, which mesh with a pair ofrelatively large gears 25, each of which is provided with an outwardlyextended trunnion 26 journaled in bearings 27 bolted to the webs of theside members 6 and extend through apertures formed therein.

The gears 25 are connected by an eccentrically located pin 28, in whichis secured one end of a connecting rod 29. The other end of theconnecting rod 29 is extended between a pair of transversely spaced lugs30 on the cross head 16 and connected thereto by a pin 31. The forwardstroke of the cross head 16 is such as to cause the plunger-s 15 totravel completely through the feed passageway 1d and project materiallyinto the bushings 1() forward of said passageways.

Obviously, the above described driving connections, from the drivenshaft 18 to the connection rod 29, are arranged to balance straight-linemovementto the plungers 15:

in the bushings to prevent the same from binding or causingunduefriction.

During the forward'movement of the plungers 15, portions of thematerials in the feed passageways 14 will be forced into the forwardportions of the bushings 10 and compressed to form briquets Z. At thecompletion ofeach forward stroke of the plungers 15, three briquets areformed, one in each bushing 10 and likewise, three of the "completedbriquets are forced through or from the contracted delivery ends of saidbushing. 7 .o

It will be noted that the length of-the bushings 10 is such as to hold aplurality of formed'briquets Z, and the friction be tween the briquetsand the bushings, which is materially increased by the contracted endsof said bushings, is suchas to retard the movement ofthe'briquets duringthe forward stokeof the cross head, so that they act as abutments,against which other bri- V quets are successively formed.

Obviously, by adjusting the nubs 13, the' delivery ends of the bushings10 may be contracted, at will; In case the bushings 10 The wastematerial from which the briquets are formed, is first ground, beforedein presence of a wear out, new ones may be substituted therer for.

livered into the bushings 10, and when the V waste from hemp is usedinmaking briquets,

the ground waste is sprayed withhot tar or other suitable material toform a binder. When the waste from flax is used in making briquets,thenatural oil therein is brought to the surface under the pressureproduced thereon by the plungers 15, and which oil acts as a binder forthe briquets. Straw or other material may also be used in the provedfuel press for making briquets The above describedinvention has, in atual usage, proven highly efiicient, for the purpose had in view.

What'I'claim isz In a fuel press, the combination with a ing forcontracting the same, a plunger workingin the bushing, and means foroperating the plunger. o

In testimony whereof 1' aflix y signature witness.
